# [−][src]Function mynewt::kernel::os::os_eventq_poll

    pub unsafe extern "C" fn os_eventq_poll(
        arg1: *mut *mut os_eventq,
        arg2: c_int,
        arg3: os_time_t
    ) -> *mut os_event

Poll the list of event queues specified by the evq parameter (size nevqs), and return the "first" event available on any of the queues. Event queues are searched in the order that they are passed in the array.

- `evq`: Array of event queues
- `nevqs`: Number of event queues in evq
- `timo`: Timeout, forever if OS_WAIT_FOREVER is passed to poll.

Return: An event, or NULL if no events available

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
